Migrating from 3dcart to Wordpress - any advice ?

Hi fellas,

I purchased a 3dcart package with 2G bandwidth. Now that my visitors are starting to grow I'm exceeding my bandwidth, so I'm charged at a rate of $5 by gigabyte. I'm knocked on my teeth now !!!!

I'm thinking about migrating to wordpress CMS and hosting on godaddy (unlimited bandwidth, unlimited storage,etc.)

Is there anything I sould worry about before or after migrating (security, getting hacked..) ?

come on guys ..
